// The month id (01, 02, ...) returned by the getSelectedMonth() call
// against the stack will be auto-selected
MG>so in first case execute() would call the value getId()
MG>in the second case value is selectedMonth so execute() would call
getSelectedMonth()
Note: For any of the tags that use lists (select probably being the most
ubiquitous), which uses the OGNL list
notation (see the "months" example above), it should be noted that the map key
created (in the months example,
the '01', '02', etc.) is typed.
'1' is a char,
'01' is a String,
"1" is a String.
This is important since if
the value returned by your "value" attribute is NOT the same type as the key
in the "list" attribute, they
WILL NOT MATCH, even though their String values may be equivalent. If they
don't match, nothing in your list
will be auto-selected.

Overwrite a TypeConverter for a Map with Generics
Hello, how can i overwrite a TypeConverter for a Map? I defined the following global TypeConverter: java.lang.String=de..converter.StringTrimConverter (the converter removes blanks from the string) This converter is used for every String, even inside maps. That's fine. In one action i use the following map: Map textfield = ... How can i use the default/another String converter for this property? Using a properties file for the action doesn't work. The Entry "Element_textfield" is not used because i use Generics.

RE: Select multiple values from a dropdown
Our application has a form on the right pane where user can create a request
and submit it. After the request is submitted, it will be displayed on the
left pane. The left pane lists all the submitted requests in the system.
When user selects one of the requests on the left pane, the data will be
populated in the form on the right pane. These data will be displayed in
uneditable mode until user selects the 'OPEN' request button.
The issue we have is that the values in the dropdown box display the whole
list, instead of highlighting the selected values which user has chosen.
